<dt><code>#pragma GCC visibility push(</code><var>visibility</var><code>)</code><dt><code>#pragma GCC visibility pop</code><dd><a name="index-pragma_002c-visibility-4180"></a>
|
||
|
|
This pragma allows the user to set the visibility for multiple
|
||
|
|
declarations without having to give each a visibility attribute
|
||
|
|
(see <a href="Function-Attributes.html#Function-Attributes">Function Attributes</a>).
|
||
|
|
|
||
|
|
<p>In C++, ‘<samp><span class="samp">#pragma GCC visibility</span></samp>’ affects only namespace-scope
|
||
|
|
declarations. Class members and template specializations are not
|
||
|
|
affected; if you want to override the visibility for a particular
|
||
|
|
member or instantiation, you must use an attribute.
